Reason I ask is because I've never really paid much attention to the cooling rate, but I'm currently running a 10 zone oven and using all 10 zones for heating whereas I've almost always used a 10 zone as 9 heating and the last as a cooling. I'm curr

The ideal cooling zone curve should be a mirror image of the reflow zone curve. The more closely this curve mimics the reverse of the reflow curve, the tighter the grain structure of the solder joint will be upon reaching its solid state, yielding a

Solder paste has stencil life time - if you go over it means you should change it. If you print boards in front and keep them for too long before reflow, the flux is still evaporating, so you are not mitigating the risk. Paste also likes room tempera

If you're asking me, I'm using BLT LFS-UFP-T4 (they have an even better paste to treat badly now if you add zq). Those in the test of the world might find Loctite GC10 is similar, however the stencil and tack times on the BLT are pretty awesome and
